Yes. I understood that too. Now I get it. I took it one by one(sequantially). But since it was in equilibrium, it must have been calculated simultaneously, as you said. Many thanks @haruspex

The last 2 pictures don't show up for me, so I'm uploading them here again.(My solution with the lami theorem.) NZ is found to be 20 from this equation

No, That's not what I mean. Let me try to explain this through an example. A force of 20 N is applied to a square object. The question is what is the reaction force of the surface? (In the below picture). We found Nsurface as 12 N. Because we did not include the x component of force in the...

Question: Neglect friction and motion (sliding) and G(sphere)=20N. What is the reaction force exerted by the surface Z on the sphere?. In this question I reached two different result with two different solving method. But one of them is false according to answer key. My question is why first...

In the second picture, the first calculation(yellow writings), what I did was to find the reaction force of the X surface. Second calculation(green writings) was to find the reaction force of the Z surface!

Yes, what I've done is this: Dividing the vectors into their x and y components and thus finding the reaction force of the Z surface.

sorry I forgot it. The question is: What is reaction force of Z surface to the sphere?

neglect friction and motion (sliding) and G(sphere)=20N. In this question I reached two different result with two different solving method.But one of them is false according to answer key. My question is why first solving way is false? Because the first solution way makes sense to me. If we...
